wouldn't serve its role, which is to deter crime I wouldn't say that is the sole role of prisons. They kind of have 3 functions: 1. To remove a troublesome individual from society. 2. To rehabilitate an individual. 3. To disincentivize crime (as you say). In our society they are often talked of as having a further role to "punish" an individual. I guess this may actually effect policy, which I guess is effectively revenge. This doesn't seem like a useful notion however. I'm not sure that prisons being nicer would really make me consider crime as a more viable option. It sounds pretty bad even if I don't consider the culinary options.
